Question

我正在尝试实现一个接受json字符串的web服务，并根据它获取.zip文件的密钥。

然后我需要发送.zip文件和捆绑在多部分数据中的json字符串。

所以基本上我的回答应该是一个包含两个部分的多部分对象

1) .zip file
2) json string

这是我目前的代码

public class ContentRepo {



@POST
@Path("/fetchModel")
@Consumes("application/json")
@Produces("multipart/mixed")
public Response getContent(String strJson)
{
    Response response = null;
    try{
        JSONObject objJson = new JSONObject(strJson);
        String strAssetName = objJson.getString("assetName");
        if(null != strAssetName){
            Client client = ClientBuilder.newClient();
            ResteasyClient restEasyClient = (ResteasyClient) client;
            ResteasyWebTarget target = restEasyClient.target("http://localhost:8091/ContentServer/").path("fetchModel");
            response = target.request()
                    .post(Entity.entity(getMultiPartData("Car"), MediaType.MULTIPART_FORM_DATA));
        }
    }catch(Exception ex){
        ex.printStackTrace();
    }

    return response;
}

public MultipartFormDataOutput getMultiPartData(String strAssetName){

    MultipartFormDataOutput objMultiPartData = new MultipartFormDataOutput();
    JSONObject objJson = new JSONObject();

    try{
         if(strAssetName.equalsIgnoreCase("Car")){
            //car assets
            try {
                objMultiPartData.addFormData("file", new FileBody(new File("D:/programs/content_server/Car/Car.zip")), MediaType.APPLICATION_OCTET_STREAM_TYPE);
                objJson.put("png", "car");  
                objMultiPartData.addFormData("mapping", new StringBody(objJson.toString()), MediaType.APPLICATION_JSON_TYPE);
            } catch (UnsupportedEncodingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }catch(Exception ex){
        ex.printStackTrace();
    }

    return objMultiPartData;
}

}

然而，当运行上面的时候我无法获取多部分响应。而是获得以下异常

您的堆栈跟踪抱怨说，在constructor版本3.0之前找不到ResteasyProvider introduced org.jboss.resteasy:resteasy-jaxrs才能支持org.jboss.resteasy:resteasy-client 。因此，您可能在运行时类路径的某处有一个较旧版本的resteasy-jaxrs。删除它并确保已部署的应用程序的resteasy-jaxrs和resteasy-client版本同步。
